and aggregated non-overlapping ratio of a set of intents.  ...  In this work, unified models are proposed to rank intents underlying a query by combining relevance score and diversity degree, in which the latter is reflected by non-overlapping ratio of every intent  ...  NOL Ratio for a Set of Intents Another solution views the intent ranking as an optimization problem that maximizes the aggregated NOL (ANOL) ratio of an intent set, which is the ratio of aggregated unique  ...

Interest and Evaluation of Aggregated Search

Arlind Kopliku, Firas Damak, Karen Pinel-Sauvagnat, Mohand Boughanem
2011 2011 IEEE/WIC/ACM International Conferences on Web Intelligence and Intelligent Agent Technology  
In this paper, we conducted a user study which was designed to revisit and compare the interest of aggregated search, by exploiting both relevance by intent and content, and using both short text and fixed  ...  Aggregated search is relatively new and its advantages need to be evaluated.  ...  The facts that vertical intent is often present within Web search queries and that aggregated search produces a diverse set of relevant results can prove partly the interest in aggregated search.  ...

IntenT5: Search Result Diversification using Causal Language Models [article]

Sean MacAvaney, Craig Macdonald, Roderick Murray-Smith, Iadh Ounis
2021 arXiv   pre-print
Across six standard evaluation benchmarks, we find that our method (which we call IntenT5) improves search result diversity and attains (and sometimes exceeds) the diversity obtained when using query suggestions  ...  Existing approaches often rely on massive query logs and interaction data to generate a variety of possible query intents, which then can be used to re-rank documents.  ...  We generally find that our IntenT5 approach can improve the search result diversity for both lexical and neural models, when aggregating using either PM2 or xQuAD.  ...

Evaluating large-scale distributed vertical search

Ke Zhou, Ronan Cummins, Mounia Lalmas, Joemon Jose
2011 Proceedings of the 9th workshop on Large-scale and distributed informational retrieval - LSDS-IR '11  
Building a large-scale test collection for aggregate search is costly in terms of time and resources.  ...  Aggregating search results from a variety of distributed heterogeneous sources, i.e. so-called verticals, such as news, image, video and blog, into a single interface has become a popular paradigm in large-scale  ...  Aggregated search deals with such diverse heterogeneous information and interaction data, that previous research into distributed test collections (e.g. those conducted on newswire collections) cannot  ...

Composite retrieval of heterogeneous web search

Horatiu Bota, Ke Zhou, Joemon M. Jose, Mounia Lalmas
2014 Proceedings of the 23rd international conference on World wide web - WWW '14  
In aggregated search systems, results from different and increasingly diverse verticals (image, video, news, etc.) are returned to users.  ...  For instance, many such search engines return to users both images and web documents as answers to the query "flower". Aggregated search has become a very popular paradigm.  ...  Acknowledgments This work was partially funded by the Linguistically Motivated Semantic Aggregation Engines (LiMoSINe 3 ) EU project.  ...

Aggregated Search Result Diversification [chapter]

Rodrygo L. T. Santos, Craig Macdonald, Iadh Ounis
2011 Lecture Notes in Computer Science  
Finally, we generalise standard diversity metrics, such as ERR-IA and α-nDCG, into a framework for evaluating diversity across multiple search verticals.  ...  In this paper, we empirically investigate the need for diversity across four different verticals of a commercial search engine, including web, image, news, and product search.  ...  ., documents, images, videos, maps) in the increasingly prevalent aggregated search interfaces of modern search engines, we propose to generalise intent-aware metrics into a framework for evaluating diversity  ...

An Overview of Aggregating Vertical Results into Web Search Results

Suhel Mustajab, Mohd. Kashif Adhami, Rashid Ali
2013 International Journal of Computer Applications  
Aggregating verticals into the core web results helps in achieving diversity in information search.  ...  Various vertical selection approaches and design and evaluation of aggregated search interfaces have been discussed which has been a less focused area as compared to the most prior research work in conventional  ...  BACKGROUND Aggregated search is analogous to federated search, in which diverse information can be collected from various resources such as databases, web-based search engines, library catalogues and corporate  ...

Temporal variance of intents in multi-faceted event-driven information needs

Stewart Whiting, Ke Zhou, Joemon Jose, Mounia Lalmas
2013 Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13  
Effective diversity is reliant on methods to (i) discover and represent facets, and (ii) determine how likely each facet is the user's intent (i.e., its popularity).  ...  In this work we study the temporal variance of search intents for event-driven information needs using Wikipedia.  ...  Despite ongoing temporal change, existing approaches to multifaceted intent diversity assume a static set of search intents and likelihood (popularity).  ...

Microsoft Research Asia at the Web Track of TREC 2009

Zhicheng Dou, Kun Chen, Ruihua Song, Yunxiao Ma, Shuming Shi, Ji-Rong Wen
2009 Text Retrieval Conference  
In TREC 2009, we participate in the Web track, and focus on the diversity task. We propose to diversify web search results by first mining subtopics, and then rank results based on mined subtopics.  ...  Our experimental results show that the model improves diversity of search results in terms of α-NDCG, and combining subtopics from multiple data sources helps further improve result diversity.  ...  The aggregator then collects and aggregates all results and returns them to the client.  ...
